Definitions

  • the invention relates to a paving or revetment comprising a top surface and a conveying element for conveying liquid, such as water, along the top surface and for the transfer of heat between the top surface and the liquid.
  • the heated water is then stored in the ground or is conveyed for space heating through buildings adjoining the road.
  • a solar collector system can also be used for subsequently making the stored energy available for keeping surfaces free of ice, such as, for example, carriageway surfaces in the case of bridges or locks.
  • the embedding of a pipe system in a paving of, for example, a road surface or aircraft runway is relatively expensive by comparison with the costs of primary energy, while the heat gained (exergy) is of low quality.
  • the paving disclosed in document AU 524 990 B comprises a top surface (top of casing 2, fig.3) and a conveying element (core 1, fig.3) for conveying a liquid along the top surface, and for the transfer of heat between the top surface and the liquid.
  • the paving furthermore comprises a top layer (top of casing 2, fig.3) with a porous layer (core 1, fig.3) underneath it having possibly 20% voids (page 3, lines 3-5).
  • a sealing layer (bottom of casing 2, fig.3) situated beneath the porous layer is also present, and discharge elements (3, 4, fig.3) are provided in a longitudinal direction.
  • the discharge element (4, fig.3) connects to the porous layer for the discharge of the liquid from the layer, and at a distance from the discharge element, a supply element (3, fig.3) connects to the porous layer for the supply of liquid to the porous layer.
  • the manufacturing of the apparatus according to AU 524 990 B requires the top layer being part of a casing surrounding the core of the apparatus. It thus impossible to construct the top layer by asphalt spreading.
  • the object of the present invention is a method for providing a paving or revetment provided with a conveying element for heat transfer between the top surface and a liquid, such as water, which is conveyed by means of the conveying element along the top surface, and which is simple and cheap.
  • a further object of the present invention is to provide a paving with a relatively high coefficient of heat transfer between the top surface and the heat conveying element, in which the system can be overlaid in a simple manner and can be reused during replacement or renovation.
  • a paving or revetment according to the present invention is characterized in that the resulting paving comprises a top layer with a porous layer underneath it having at least 20% voids, and a sealing layer situated beneath the porous layer, a discharge element being provided in a longitudinal direction, which discharge element connects to the porous layer for the discharge of the liquid from the porous layer, and at a distance from the discharge element provision being made for a supply element extending in the longitudinal direction and connecting to the porous layer for the supply of liquid to the porous layer.
  • the top layer of the construction according to the present invention has both the function of paving layer or revetment layer and that of absorption surface.
  • the paving according to the invention has the same bearing power value as a corresponding construction without heat conveying properties and with only an additionally required layer thickness varying between 0 and 2 cm.
  • the solar collector according to the present invention can be placed by means of the existing techniques for road surfacing, for example by means of an asphalt spreader, so that its cost is very low. Furthermore, the solar collector according to the invention has a relatively high coefficient of heat transfer by comparison with a system of pipes embedded in the road surface.
  • Such plastic pipes with a diameter of 1 to 2 cm, lying approximately 6 cm beneath the surface of the paving with a centre-to-centre distance of 6 to 12 cm, are not only expensive, but also relatively inefficient.
  • the system according to the present invention can be provided in a simple manner with a new layer of paving material which has the same properties, for example for maintenance of the paving.
  • the pipes would ultimately lie too deep down, while cutting away the top layer can lead to damage to the pipe system.
  • the solar collector according to the present invention is composed completely of materials which are in standard use in roadbuilding for paving the wearing course, and which can be reused in their entirety after cutting away and grinding during renovation of the system. This is of great importance, since asphalt top layers have a useful service life of 10 to 15 years.
  • Construction and alterations, such as road diversion or road widening, may also be necessary, and these can be carried out in a simple manner with the solar collector according to the present invention.
  • the porous layer used preferably comprises a layer of very open-textured asphalt concrete with a predominant granule size between 6 mm and 8 mm, or between 8 mm and 11 mm, or between 11 mm and 16 mm, and with a voids ratio of at least 20%, preferably between 25 and 30%. Water can flow with low flow resistance horizontally through such a layer, from the inlet to the outlet.
  • the outlet of the porous layer is connected to a heat storage means, for example by way of a pump or heat pump, while water is conveyed by way of the inlet from a storage medium to the porous layer.
  • the top layer of the paving can be water-impermeable, in order to prevent the water to be heated from becoming polluted, so that, for example, it cannot or must not be pumped back into the ground. It is also possible to make the top layer an open construction, in order to obtain good water drainage, and in order to place a thin water-impermeable asphalt layer or other impermeable layer such as a geotextile or a plastic or bituminous membrane between the open top layer and the conveying layer.
  • the top layer can be made porous, while the voids ratio is preferably kept of the same order of magnitude as that for the porous liquid conveying layer, but with the granule diameter of the top layer preferably being predominantly between 2 and 4 mm.
  • the individual pores then become much smaller, so that water is able to flow easily towards the coarse-grained intermediate layer lying below, but so that (coarse) dirt is not allowed through. Fine dirt (sludge) is removed with the continuous stream of water which is conveyed through the porous layer along the wearing course to the drain construction.
  • the invention is very suitable for use on motorways or as a paving for dikes and coastal defence structures, and the following five advantages are obtained:
  • So-called double-layer very open-textured asphalt concrete which can be used in a suitable manner as a solar collector of the type described above is manufactured by applicant under the brand name of DUOLAY.
  • the lateral gradient of the road can be used, said gradient where present being approximately 2%.
  • the supply element and the discharge element can be formed by a simple channel construction.
  • an artificial drop can be created by providing the supply element at a raised level relative to the bottom of the discharge element, so that the water is pushed through the porous layer under the influence of the pressure gradient created by the increased height of the water in the supply element.
  • the channel constructions will be closed, in order to prevent soiling.
  • the system resulting from the method according to the present invention can be used not only for heat storage in the groundwater, but also for keeping the wearing course free of ice. Should the porous intermediate layer freeze up, no damage will be caused in that case. Supplying warm water to the porous layer means that gritting costs can be reduced substantially and less damage is caused to the environment by salt.
  • the paving according to the invention can also be used as a dike revetment, where the latter may or may not act as a wearing course.
  • the solar collector When the solar collector is used on a bridge surface, the solar collector can be used for heating the bridge surface itself; when used on a road surface, the road surface can be heated or buildings situated along the road can be heated, and the solar collector can be connected to a heating/air conditioning system of such a building.
  • the building below can be heated
  • the supermarket which may be adjacent can be heated. In the case of an airport apron or runway the departure lounges or the working areas etc. can be heated.
  • Figure 1 shows a lateral cross section of a paving 1 provided with a base course 2 of asphalt, sand cement, concrete etc.
  • This base course 2 is placed on a foundation of concrete or sand.
  • a sealing layer 3 approximately 2-4 cm thick, for example in the form of a watertight asphalt layer, is placed on the base course 2.
  • a porous layer 4 is formed by, for example, a layer of very open-textured asphalt concrete with a thickness of approximately 4-6 cm and with a voids ratio between 25 and 30%.
  • the particle size of the porous layer 4 lies predominantly between 6 mm and 8 mm, or between 8 mm and 11 mm, or between 11 mm and 16 mm.
  • the porous layer 4 is covered by a top layer 5, which forms the wearing course of the paving, and which is, for example, formed by a layer of asphalt concrete with a relatively low voids ratio and a thickness of approximately 3 to 5 cm.
  • the layers 2, 3, 4 and 5 have both the function of paving layer which meets the traffic requirements as regards load and that of solar collector, in the case of which the dark properties of the top layer 5 make it very suitable for absorbing solar heat.
  • Figure 2 shows an embodiment in which, as a result of the gradient of the road surface, which is, for example, 2%, the water is conveyed through the porous layer 4 from a supply element 6 to a discharge element 7.
  • the supply element 6 can connect to the porous water-conducting layer in the dense base course 2, which in this case is designed as a channel around the porous layer 4.
  • a pipe system situated in the longitudinal direction of the paving can be connected to the supply element 6 and the discharge element 7. It is also possible for a separate channel to be provided along the supply elements 6 and discharge elements 7, which are provided at regular mutual intervals.
  • the sealing layer 3 is preferably of an insulating design, and said layer comprises, for example, asphalt with lightweight granules or cellular concrete. This will make the temperature of the porous layer rise more quickly, and the efficiency of the solar collector increases.
  • the wearing course is horizontal and the supply element comprises a channel 9 whose bottom 10 is formed by the porous layer 4.
  • the discharge element is formed by a channel 8 whose bottom 12 is situated at a lower level than the bottom 10 of the channel 9.
  • Part of the side wall 11 of the channel 8 is formed by the porous layer 4, and water is conveyed through the porous layer from the supply channel 9 to the discharge channel 8 as a result of the difference in height between the water levels in channel 9 and channel 8.
  • the water heated in the porous layer 4 can be used directly for heating buildings or can be stored in the deep groundwater. According to requirements, the warm groundwater can be pumped up again and used for heating, either of the paving 1 by supplying to the supply opening 6 or the supply channel 9 or for heating of buildings situated near the road surface.
  • a suitable combination of top layer 5 and porous layer 4 is formed by a two-layer very open-textured asphalt concrete construction such as that manufactured by applicant under the brand name of DUOLAY.
